Form Traveller System Bridge Construction: Out-spanning Traditional Methods
The use of form traveller systems offers significant cost savings for bridge construction projects throughout the world. We've partnered with Miguel Barreto from ConstruGomes of Portugal to highlight the key aspects of form traveller systems: how they offer cost advantages over traditional construction systems, in what situations they can best be utilized, and how they function.
Form Traveller Bridge Construction
Form traveller specifics.
Form travellers can be employed during cantilevered concrete girder construction when a bridge pier can be used as a starting point. Opposite directions of span construction are facilitated by using the top of a pier as the initial anchor point for two separate form travellers (each pair of form travellers operates as a unit). Cantilevered construction is allowed by moving each pair of form travellers farther away from a pier in tandem. The weight is therefore always balanced, and the static forces on the pier maintain equilibrium. The incremental movement of each pair of form travellers is the critical path to project completion.
Work progress is limited to span increments of approximately 5 m (approx. 16') or 400 tons per week on each side of a pier. However, the key advantage of form travellers is their ability to span great distances in remote locations. If the contractor can access the piers, the bridge can generally be built with form travellers, including angled bridge decks with varying turn radii. Form travellers are preferred for building spans over deep valleys, waterways, and roads where access from the ground is a challenge and the number of piers is limited (especially for the central span).
- Form Traveller Delivery: Form traveller equipment can be trucked to the job site in multiple shipments or barged to the site if a bridge is being constructed over a navigable waterway.
- Form Traveller Operation and Training: Form travellers are powered by a hydraulic system, requiring the crews that operate them to receive specific training. The structural framework of the form traveller moves forward on rails anchored to the previously constructed span segments. The individual steel structural members of each form traveller are connected with pins to facilitate mobilization/demobilization.
- Form Traveller Installation: Form traveller equipment is assembled on the ground, and segments are then lifted by crane to their starting points on a specific bridge pier. Demobilization follows the same process in reverse. Sections are placed on the ground by crane and further disassembled into shippable parts.
Form Travellers vs. Traditional Construction
The main advantage of form travellers over other construction methods is that they allow for longer and wider spans to be built in challenging site conditions. Form travellers are better suited for bridge designs involving fewer piers because they can span much greater distances than other methods. This chart generically summarizes the maximum spans, widths, and timelines allowed by various concrete bridge construction techniques.
Moving Scaffolding Systems (MSS)
Moving scaffolding systems (MSS) cannot take full advantage of cantilevered construction techniques as compared to form travellers. Customized (expensive) MSS equipment is required for bridge decks greater than 20 m (approx. 65'). Moving scaffolding systems can be more cost-effective for long bridges with equal repeated spans (or multiple spans) because it is generally a quicker method: 30–60 m (approx. 98–196') span every week, or 60–90 m (approx. 196–295') span every two weeks. For bridge decks with a substantial turn radius, the MSS become less easy to operate. The MSS structure has to extend outward and move around constructed bridge piers as shown in this video .
Incremental Launching
Incremental launching is preferred for long straight bridge spans or those with a large and constant turn radius. This method becomes less feasible when the design requires an angled bridge deck relative to the horizon or a flat deck with a varying turn radius. The placement of each span increment is limited by the size of the hydraulic system pushing each span segment into place. Initial installation costs of the launching equipment (cables, hydraulics, rollers, etc.) is high, generally becoming more cost-effective as total bridge lengths approach 400 m (approx. 1,312'). It is usually good for small wide bridge decks that can be built in consistent segments, such as railroad bridges. It is also a good option in places where the bridge is high because the contractor doesn't need to use cranes or transports along the bridge to place deck segments. Concrete and steel materials are staged at a consistent location, so the system works similarly to a production factory.
Pre-Cast Materials
Pre-cast construction is often not suitable for larger spans. The length of the pre-cast concrete members is limited by factory equipment, the behavior of formed concrete, and shipping considerations. The use of pre-cast members is not feasible in some remote areas due to poor access roads. Transporting and elevating pre-cast members with cranes can be particularly challenging for bridge projects with poor access, rivers, or low support conditions. The higher a project’s bridge piers, the higher the cost of crane operations (i.e., larger crane equipment is required).
Heavy Propping and Traditional Scaffold Formwork
When the bridge spans are located at significant heights above grade, traditional formwork becomes no longer feasible since it requires bracing to ground. It becomes more labor-intensive and tedious as span lengths and pier heights increase. ConstruGomes has used heavy propped formwork up to only 40 m (approx. 131') of bridge span and height. These systems are normally limited to a height of 40 m because of material limitations and safety considerations. The spans can be large because they can have multiple support towers on the ground. The limit of 40 m of span is between a set of propping towers only.
Self-Climbing Formwork
Self-climbing formwork operates similarly to form travellers but builds piers vertically in increments as opposed to bridge decks laterally. Self-climbing formwork is installed at grade and can be used to construct the entire height of a new cast-in-place concrete pier. Lifts of up to 5 m (approx. 15') every 2–3 days can be achieved. Self-climbing formwork needs a constructed pier height of only 1 m (approx. 3') to begin operations.

What Is Form Traveler In Construction?
- Building & Construction
A form traveller is a type of travelling formwork system used in bridge construction. It enables the repeated construction of structural elements and is typically used for free cantilever construction of post-tensioned box girder and cable-stayed concrete bridges.
Form travellers are supported by the part of the structure already built, and can be overhead or underslung
Form traveller is a system used for free cantilever construction of post-tensioned box girder and cable-stayed concrete bridges. It is lightweight, versatile, easy to assemble and operate, rolling forward on rails or rollers, and supports the weight of the construction elements including formwork, traveler, reinforcement and uncured concrete.
The form traveller system is designed to be highly stable and rigid so that it does not move significantly under the weight of the concrete as it is poured or during curing. It also has features such as being portable and cost effective.
The Standard form traveller is intended to be used for bridge construction and has a maximum segment length of 5 meters. The load capacities for concrete and formwork can range from 250 to 400 tonnes. The weight of the steel used in the form traveller depends on the specific cross-section of the bridge, typically ranging from 25 to 65 tonnes.
It is possible to modify the Standard form traveller to fit almost any cross-section and adjust it during use to accommodate changes in segment length, section height, web thickness, and deck width.
What Is Form Traveler Used For?
Form travellers are used for free cantilever construction of post-tensioned box girder and cable-stayed concrete bridges. They are lightweight, versatile, easy to assemble and operate, rolling forward on rails or rollers, and offer significant cost savings over traditional methods.
Form travellers are preferred for building spans over deep valleys, waterways, and roads where access from the ground is a challenge and the number of piers is limited.
The main advantage of form travellers over other construction methods is that they allow for longer and wider spans to be built with less material than traditional methods.
Form travellers come in two types: overhead form travelers which are suspended underneath the bridge structure already erected, and under-slung form travelers which are mounted on top of the structure already erected.
Is Form Traveler Used For Construction Of Superstructure?
Form travelers are commonly used for the construction of cantilever segmental bridges, as they provide a convenient and efficient means to build superstructures.
These form travelers give shape to the segment, support the weight of the newly cast concrete until it has gained enough strength to be post-tensioned to the previous cantilever segments, and transfer the segment weight to the already existing superstructure.
Form travelers can also be used in certain circumstances for other types of bridge structures (such as truss or arch bridges), depending on the specific design requirements.
Form Traveller Installation
Installation of form traveller involves assembling the equipment on the ground and lifting segments by crane to their starting points on a specific bridge pier.
Form travellers come in two main types: overhead and underslung, with both being designed for free cantilever construction of pre-stressed girder and cable–stayed concrete bridges.
Structural analysis is used to improve the performance and alignment of bridges, as well as ensure that the formwork does not move significantly under the weight of the concrete during pouring or curing.
Form Traveller Components
Form traveler components consist of a main frame, walking and anchoring device, bottom mould frame, side mould frame, inner mould frame, front lifting device and rear lifting device which are important for the smooth functioning of form travelers.
The main frame provides stability to the whole assembly while the walking and anchoring devices assist in its movement. The mould frames form an enclosure for supporting the form structure pieces and the lifting devices on both ends help in moving them between different levels.

BRIDGEBUILDER FORMTRAVELLER
Travelling formwork system for free cantilever construction.
BRIDGEBUILDER Enhance The Economic Performance of Bridge Projects.
Reliable Bridge Construction Equipment for Free Cantilever Construction with NRS Innovation and Solutions.
“BRIDGEBUILDER” FORMTRAVELLER
The Overhead and Underlane NRS Formtraveller which is widely and well known as the Bridgebuilder, is the most reliable and extensively used FormTraveller system in the world for in-situ construction of free cantilever post tensioned box girder bridges as well as cable-stayed concrete bridges.
It has been adopted as the de facto design that is widely used among all suppliers in the industry.
To date NRS has supplied more than 1000 units of Bridgebuilder worldwide.
The “Bridgebuilder” formtraveller system was invented in 1970 and today it is acclaimed for enhancing the cost-effectiveness of bridge projects worldwide.
The Bridgebuilder has undergone vast improvements over the years and incorporated innovative solutions, making it a developed, practical and reliable system for contractors.
Today the Bridgebuilder is a versatile, lightweight, easy-to-assemble and operate.
The system is designed with the following cost savings solutions:
- Special “Fast-Split” installation method on hammerhead as short as 7m long.
- NRS Bridgebuilder with cross member for Hammerheads as short as 3m.
- Back launching to pier for ease of dismantling after use
- Use of Bridgebuilder for casting hammerhead
- Casting closure segment stitches.
STANDARD CONVERTIBLE BRIDGEBUILDER
The Standard Bridgebuilder is designed for a maximum segment length of 5 m and load capacities (concrete and formwork) varying from 100 tons to 400 tons. The steel weight depends on the cross-section of the bridge in question, but will normally vary from about 25 tons to 65 tons correspondingly. The Standard Bridgebuilder may be adapted to suit almost any cross-section, and is easily adjustable during operation to variations in segment length (up to 5 m), section height, web thickness, and deck width.
TAILORED BRIDGEBUILDERS
The Bridgebuilder may be tailor-made for segment lengths beyond 5 m and other extreme conditions. Alternatively it may be designed for shorter lengths where the maximum segment length is less than 5 m, and there is a requirement to reduce the weight of the Bridgebuilder for a particular application.
NRS Special Bridgebuilder for arch bridge construction has also been used successfully for the construction of the 323m arch bridge at the Hoover Dam Bypass project – the longest arch bridge in North America and the 4 th longest concrete arch bridge span in the world.
Modern bridges are becoming wider and longer but at the same time clients and contractors are seeking shorter construction time. In NRS, pursuing improved and innovative solutions to meet these requirements has always been one of NRS main goals.
NRS never fails in giving innovative designs even for conventional equipment like the Formtraveller
THE BRIDGEBUILDER FEATURES
- Lightweight
The use of rectangular hollow sections in the main structural components and recoverable high strength bars in all stays and ties reduces the total steel weight to a minimum.
- Versatile and Flexible Design

- Small Deflections
The vertical deflection at the front of the Bridgebuilder is less than 25 mm at maximum load. Formwork beams are designed for a maximum deflection of 1/400 of their length.
- Easy Assembly and Operate
-One Bridgebuilder may be assembled in one week. Rolling forward on rails, the reset time is short.
-Lifting system to lift and install the whole Bottom slab for Overhead BB FT and the whole pre-assembled on ground Underlane BB FT.
– Rebar Carrier and trolley system
SPECIFIC DETAILS
Technical principle & working cycle.
A normal working cycle may be as follows:
- The Bridgebuilder, except for the internal formwork, is launched into position for a new segment
- The external formwork is levelled and fixed.
- Bottom slab and webs reinforced.
- The internal forwork is pulled forward.
- Concreting of bottom slab and webs. The top slab may be cast after a short intermission to allow setting of the concrete in the webs, or it may be cast the next day.
- After sufficient concrete curing, post-tensioning takes place.
- Form work is loosened, and the Bridgebuilder launched forward to the next segment. In most cases one cycle is carried out in one week. There are examples of 4-5 days cycle.
MAIN PRINCIPLE & COMPONENTS
Cross-Member For Installation On Small Pierheads
When the pier head is too small to allow normal assembly of the Bridgebuilder, our patented Cross-member solves the problem. It makes it possible to start free cantilevering from pier heads as small as 3 m. The procedure is illustrated through the above 4 phases.

Free cantilever method
- Certificates
This method of constructing a bridge structure is used mainly for bridges spanning deep valleys or for inaccessible terrain. An optimal span suitable for free cantilevering is 60 m – 150 m, but bridges with a considerably larger span are commonly realised.
The free cantilever technology consists in developing the bridge structure by individual parts, the so-called segments. Segments are concreted into formwork fixed to a special movable steel structure – form traveller. An optimal design and weight of the form traveller is fundamental for the design and economic advantageousness of the given structure.
VSL offers the so-called modular system of form travellers, which can be applied to bridge structures with different cross-sections and lengths of segments. The lightweight system of VSL form travellers has minimal demands on lifting equipment at installation at the beginning of construction and enables at the same time an easy access to all work fronts during the construction. The typical working cycle takes five days with 12-hour shifts and with the construction crew alternating in two form travellers. In case of need, the form traveller may be equipped with a system for steam curing, which reduces the working cycle to four days.
Welcome to the official website of Nantes Crane, the world leading Cranes and Crane Components Service Provider.
Form Traveller
Product Description
The form traveler (Called Bridge Builder) is common equipment for the construction of large-span pre-stress bridges which use cast-in build method. It can be used to build the segment one section by one section without supports and the help of large cranes.
The form traveler is a load-bearing frame that can slide or roll along the top of the bridge deck. It is anchored and suspended on the constructed beam section. The form traveler can be used for the installation of the next beam section’s formwork, reinforcement, pre-stressed pipes, concrete pouring, pre-stress tensioning, grouting and other operations. After completing the cycle of one segment, the form traveler can move forward and fixed to carry out the suspension grouting of the next segment, and so on until the cantilever grouting is completed.

Making Art From the Unexpected at Milan Design Week
Designers are showing off some of their latest works at the annual festival of furnishings and household objects.
By The New York Times
This article is part of our Design special report previewing Milan Design Week.
Designers are by definition manipulators — of materials, senses and expectations. There is nothing they like better than making the beholders of their creations stop in their tracks. At the Salone del Mobile, in a show devoted to emerging designers that runs through Sunday, visitors may be arrested by a cushion that resembles a big colorful, softball and sits like an egg in a nest of polished wood sticks. What is it? An ottoman, naturally. A few other eye catchers and head scratchers are presented below.
Another Approach to Seating
After studying industrial design at the University of Notre Dame, Ryan Twardzik tried his hand at footwear, accessory and graphic design. But “all I wanted to do was furniture,” he recalled. Moving to Schuylkill County, in Pennsylvania, in 2021, he had access to local manufacturers, including a metal fabricator who primarily built roller coasters. That led to his furniture company, Unform Studio, and its debut collection, Drip, a series of fluoro-colored chairs formed of bent metal sheeting. “I want to make things that are not just fun to look at, but also fun to touch and interact with,” he said.
Mr. Twardzik is showing works from two new collections at SaloneSatellite, the presentation of young designers that runs concurrently with the Salone del Mobile. The first, Spherae, is a ball-shaped cushion supported by three polished wood dowels that slide through a brass disc and lock into place.
“I’ve been calling it passive joinery,” Mr. Twardzik said, because the construction, inspired by foldable camping chairs, does not require tools for assembly. The stool or ottoman comes with four different cushions resembling giant, fruit-toned softballs that can be swapped out. “You can just pop whichever color you want on there,” he said, “and the other three live around the piece.”
The designer is also showing an armchair from his Pop-Up collection. Formed of 20 metal posts wrapped in upholstered foam cylinders, it functions loosely like a soft-touch bed of nails. “They pop up at different heights. Some to arm and back height and some to a shorter seat height,” he said about the components. The experiments, he added, are far from over: “There are so many ways to explore how to make a chair.”
On view Tuesday through Sunday at Salone del Mobile, Pavilion 5, Booth C17; unformstudio.com . — LAURA MAY TODD
Exploring the Sound of Color
Last year at peak times, visitors to “Shaped by Water” — Google’s Milan Design Week offering — stood in line for up to two and a half hours to be admitted.
Inside the exhibition, they experienced light and sound waves passing through water in humming, resonant bowls (some visitors started hugging them), and a planetarium-style music and light show. “We had some people coming back three and four times,” said Ivy Ross, Google’s vice president of hardware design, who oversaw the project.
Now Google is switching elements with a celebration of color, partnering with the California arts and research lab Chromasonic to create the installation “Making Sense of Color.”
Thanks to Chromasonic’s technology, which translates light waves into sound and sound waves into light, visitors who pass through “Sensory Field” — 21 spaces at the beginning of the installation separated by translucent scrims — are able to “hear” the visible spectrum, in the form of shifting melodic tones.
Johannes Girardoni, a founder of Chromasonic, said this experience creates “an atmosphere in which physical space appears infinite, at other times enveloping.”
Elsewhere in the exhibition the design team has unpacked how color feels and what it tastes and smells like. The final space presents a tableau of Google products in different colors, like the Google Pixel Watch 2 and the Pixel phone.
“It’s kind of a reveal that brings it all together,” Ms. Ross said.
She added that she hopes visitors will gain a new appreciation for color’s many dimensions. “After having the experience of what does it sound like, feel like, taste like, look like,” she said, “they’ll never look at color the same way.”

Let There Be Light
The lighting designer Volker Haug and his team have partnered with the architects at Flack Studio to create Me and You, 13 decorative lighting fixtures that have nothing to do with a dog named Boo .
The collaboration between studios, both in Melbourne, Australia, grew out of a mishap. Last year, a vintage wall sconce was being installed in a private residence designed by Flack Studio when the glass broke. Replacing the lamp meant refinishing the wall behind it, and there was no time for that. So David Flack, the firm’s founder, asked Mr. Haug, a longtime acquaintance, to create a new sconce for the square metal wall plate that was already in place.
The success of the ad hoc solution “inspired us to go, ‘Ooh, what else could we do?’” Mr. Haug recalled in a phone call from Melbourne.
The men began knocking out other ideas for lamps based on metal squares, but soon their designs “started getting longer and skinnier, or smaller or rounder,” Mr. Haug said.
The lamp called Bruce is closer to the original conception. First designed by Flack Studio for the Ace Hotel in Sydney, it was revised by the collaborators as a boxy, cast-brass grid laid over textured, glowing glass, which gives it some opacity, “like a bathroom window,” Mr. Haug said. A linear version — a single row of squares — has just been added to the collection.

Using Older Spaces for New Talent
Lionel Jadot, a Belgian designer and architect, is partial to retrofitting old manufacturing buildings. His own company, Zaventem Ateliers, occupies a 6,000-square-meter (64,583 square foot) 19th-century paper factory near Brussels. During Milan Design Week he is again transforming a run-down industrial site into a showcase for young talent.
He has organized a display of furniture, lighting, textiles and sculpture by more than 30 designers, studios and artists — mostly from Belgium but also a handful from other countries. All these works are presented in this year’s new location, a 7,300-square-meter (78,577-square-foot) 1950s industrial building near Milan’s Linate Airport, under the name Baranzate Ateliers, its second appearance at Design Week.
“I’m part of a family of makers since six generations,” Mr. Jadot said. “I know what a struggle it is to be in your workshop, to try to produce, to try to connect with people, to create collaboration.”
Many of the pieces straddle the line between furniture and sculpture. Mircea Anghel, a designer in Lisbon, makes tables and chairs from rough stones and polished wood. Studio Élémentaires in Belgium combines bits of the urban fabric (aluminum, motors, reflective filters) with LEDs to create kinetic lighting. KRJST Studio in Belgium weaves tapestries with “the monstrous creatures that haunt our dreams, not as external threats, but rather as mirrors of our own dark side,” said Justine de Moriamé, a founder with Erika Schillebeeckx of the studio, which is displaying examples of such work, including the hanging called Kappa.
The tapestries are inspired by the phenomenon of pareidolia, or the tendency to see shapes or make pictures out of randomness. “It is these harmonious or chaotic reveries that form the basis of our imaginations and personal mythologies,” Ms. Schillebeeckx added.
Baranzate Ateliers is on view Monday through Sunday at Via Gaudenzio Fantoli 16/3; baranzateateliers.com . — STEPHEN TREFFINGER
